Hi
After switching my development environment to a MacMini and using the ELDK 4.0
I discovered that my examples for building using a cross-compiler for my
PPC405 target were not correct. (Maybe a few of my previous problems were
caused by not correctly specifying the target ARCH.)
Also I would like to adapt and document the examples/common/Makefile to the
needs for cross-compiling (KSRC/XENOCONFIG/DESTDIR useage). Also I added a
target "install" to copy the generated application to $(DESTDIR)/usr/xenomai.
Hm, I don't have examples/common/Makefile in my SVN Xenomai tree. And
/usr/xenomai should be the configurable.
Could someone please commit these (or a improved version of it) patches?
Thanks in advance

A typical cross-compilation setup, in order to build Xenomai for a
-PowerPC-405-based system:
+PowerPC-405-based system (assuming an ELDK cross-compiler and a 2.6.14 kernel)
$ $xenomai_root/scripts/prepare-kernel.sh --arch=powerpc \
--adeos=$xenomai_root/ksrc/arch/powerpc/patches/adeos-ipipe-2.6.14-ppc-X.Y-ZZ.patch
\
--linux=$linux_tree
For the time beeing, we must distinguish between --arch=ppc (ARCH=ppc)
and --arch=powerpc (ARCH=powerpc). The latter is not yet supported.
$ cd $linux_tree
-$ mkdir ../build-powerpc-405-2.6.14
-$ make ARCH=ppc CROSS_COMPILE=powerpc-405-linux-gnu- O=../build-powerpc-405-2.6.14 xconfig/gconfig/menuconfig
For the ELDK CROSS_COMPILE must be ppc_4xx- for AMCC 4xx processors.

CC=ppc_4xx-gcc CXX=ppc_4xx-g++ LD=ppc_4xx-ld
$ $xenomai_root/configure --host=ppc-linux
already works fine for all ELDK tool chains. The --prefix should also
be configurable.
$ make install
